Abstract: PURPOSE:To improve the riding quality, antiskid effect and protective effect against road surface damage by a structure wherein the head of a metallic core is surrounded with rubber so as to allow the rubber contact with the ground by forming the center of the rubber in the recessed form. CONSTITUTION:The head 2 of the metallic core is surrounded with the rubber 4, at the center of which a cavity 5 is formed. The spike is fixed to the tire by driving the leg 3 of the spike into the tire. Owing to the structure as described above, because, as for the tire, the rubber 4 contacts with the ground or the core does not directly contact with the ground and as well as the cavity 5 produces negative pressure when the cavity 5 is brought into contact with the ground, the riding quality and antiskid effect can be improved and as well as the road surface damage can be prevented.

Abstract: PROBLEM TO BE SOLVED: To uniformly apply a coating material on the surface to be coated by dropping a coating material on plural circumference positions which are apart from the rotation center of a spinner in such a manner that the dropped coating material can be spread to the rotation center. SOLUTION: The spinner 11 is connected to the rotation axis 10 of a motor 9 fixed in the lower center of a chamber 8, and plural nozzles 12a to 12e connected to a photoresist reservoir are arranged in the upper part of the chamber 8.

Filed: 1988-05-30
Abstract: PURPOSE:To measure the oxygen dissolved in water by using the instrument to be used in a gaseous atmosphere by feeding nitrogen to the oxygen dissolved in water to expel the oxygen into a nitrogen atmosphere and measuring the oxygen partial pressure in the gases atmosphere. CONSTITUTION:The water to be measured is sealed into a lower space 5 of a hermetic vessel 1 partitioned to the upper and lower spaces by a partition plate 2 and the gas taken in the upper space 4 is sufficiently replaced with the gaseous nitrogen supplied from a nitrogen piping 9; thereafter, valves V1, V2 are switched to circulate the gaseous nitrogen and to feed the same into the water to be measured. The gaseous nitrogen is dissolved into the water to be measured in this way and the oxygen dissolved in the water to be measured is simultaneously expelled into the nitrogen atmosphere in the upper space 4. The oxygen partial pressure of the nitrogen atmosphere in the upper space 4 and the satd. oxygen concn. in the water are balanced in the final if the above-mentioned operation is sufficiently executed. The oxygen concn. in the water to be measured is, therefore, determined by adding temp. conditions thereto and making computation by using the prescribed equation.

Title: Viscosity measuring instrument
Inventor: HAYASHIDA SHINICHIRO
IPC: G01N11/00

Abstract: PURPOSE:To easily measure the viscosity of fluid even when a high vacuum is produced in a fluid passage by opening a fluid intake passage in a trumpet shape in a projection surface in level with the internal wall surface of the fluid passage. CONSTITUTION:The projection surface 5 of a viscosity measuring instrument 1 is in level with the internal wall surface 3a of the fluid passage 3 and the fluid intake passage 16 which is open in the projection surface 5 is open in the trumpet shape, so even if a high vacuum is produced in the fluid passage 3, for example, the high-viscosity fluid flowing along the internal wall surface 3a enters the fluid intake passage 16 naturally and smoothly and is guided inward along the trumpet-shaped wall surface. The fluid is sucked forcibly by a gear pump 6 through communicating passage parts 21a and 21b to form a continuous flow. Thus, the fluid is sent to a viscometer 7 continuously and then the viscosity is measured continuously.

Abstract: PURPOSE:To avoid damage to a gate oxide film by having a gate electrode covered with an insulator when source and drain regions are formed by ion implantation with the gate electrode as mask after it is provided on a semiconductor substrate employing a polycrystalline Si and a high-melting-point metal. CONSTITUTION:A thick field oxide film 2 is formed on the periphery of a semiconductor substrate 1 penetrating into the substrate and a thin gate oxide film 3 is applied on the surface of the substrate 1 surrounded thereby. Then, a gate electrode 4 made up of a polycrystalline Si made conductive by containing impurities or a high-melting-point metal is provided in the center of the film 3 and with the electrode as mask, an ion is implanted into a substrate on both sides of the electrode to form source and drain regions. This point, all the exposed surfaces of the electrode 4 is covered with an oxide film 5. This prevents a part of the charge contained in the ion of the impurities to reach the electrode 4 resulting in less charge to be accumulated in the electrode 4 eliminating chances to breaking the film 3.
